The singer shared a photo on Instagram Sunday, rocking a cherry red gown, matching lipstick and a whole lotta diamonds.
In the pic, she's looking at the camera with her arm resting on her head, wearing a crystal-coated pendant and diamond-covered cross necklace.
"The Oscar goes to Party ## 7!!!!! #revolutionoflove," she captioned the sultry snapshot.
According to a press release from jeweler Neil Lane, the 55-year-old was decked out in 1,000 carats of his dazzling diamonds.
The blonde beauty showed off her borrowed bling at her annual private Oscars after party at manager Guy Oseary's mansion.
If anyone can pull off that many diamonds, it's Madonna!
